Rose plant named &#39;yoyered&#39;

ABSTRACT

A distinctive cultivar of Hybrid Tea Rose plant named ‘Yoyered’, characterized by its glossy dark green leaves; long, thick and dark red stems; large golden yellow and red bi-colored flowers; and good postproduction longevity.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct cultivar ofHybrid Tea Rose plant, botanically known as Rosa hybrida, commerciallyproduced as a cut flower, and hereinafter referred to by the name‘Yoyered’.

[0002] The new cultivar is a product of a planned breeding programconducted by the Inventor in Salinas, California. The objective of thebreeding program was to develop new cut Rose cultivars with attractiveflower petal colors, long and strong stems, dark green leaves and goodpostproduction longevity.

[0003] The new cultivar originated from a cross made by the Inventor in1997 of the cultivar Pareo, not patented, as the female, or seed, parentwith the cultivar Perfect Moment, not patented, as the male, or pollen,parent. The cultivar Yoyered was discovered and selected by the Inventoras a flowering plant within the progeny of the stated cross in acontrolled environment in March, 1999, in Madrid, Cundinamarca,Colombia.

[0004] Since March, 2000, asexual reproduction of the new cultivar bygrafting on Rosa Manetti rootstocks in Madrid, Cundinamarca, Colombia,has shown that the unique features of the new cultivar are stable andreproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

[0005] The following traits have been repeatedly observed and aredetermined to be the unique characteristics of ‘Yoyered’. Thesecharacteristics in combination distinguish the new Hybrid Tea Rose as anew and distinct cultivar:

[0006] 1. Glossy dark green leaves.

[0007] 2. Long, thick and dark red stems.

[0008] 3. Large golden yellow and red bi-colored flowers.

[0009] 4. Good postproduction longevity.

[0010] Plants of the Hybrid Tea Rose can be compared to plants of thefemale parent, the cultivar Pareo. In side-by-side comparisons conductedby the Inventor in Salinas, California, plants of the new cultivardiffered from plants of the cultivar Pareo in the followingcharacteristics:

[0011] 1. Plants of the new Hybrid Tea Rose have larger flowers thanplants of the cultivar Pareo.

[0012] 2. Plants of the new Hybrid Tea Rose have yellow and redbicolored flower petals whereas plants of the cultivar Pareo havepink-colored flower petals.

[0013] Plants of the Hybrid Tea Rose can be compared to plants of thefemale parent, the cultivar Perfect Moment. In side-by-side comparisonsconducted by the Inventor in Salinas, California, plants ofthe newcultivar differed from plants of the cultivar Perfect Moment in thefollowing characteristics:

[0014] 1. Plants of the new Hybrid Tea Rose have larger flowers thanplants of the cultivar Perfect Moment.

[0015] 2. Flowers of the new Hybrid Tea Rose have more petals thanflowers of the cultivar Perfect Moment.

[0016] Plants of the new Hybrid Tea Rose have not been observed underall possible environmental conditions. The phenotype may varysignificantly with variations in environment such as temperature, light,water status and/or fertilizer type and rate, without, however, anyvariance in genotype.

BRIEF DESCRIPTION OF PHOTOGRAPH

[0017] The accompanying colored photograph illustrates the new HybridTea Rose plant, showing the colors as true as it is reasonably possibleto obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Hybrid Tea Rose. The photograph comprises a side perspectiveview of a typical flowering stem of the new Hybrid Tea Rose grown inMadrid, Cundinamarca, Colombia.

DETAILED BOTANICAL DESCRIPTION

[0018] The following observations and measurements describe cutflowering stems ofplants grown in Madrid, Cundinamarca, Colombia, inpolyethylene-covered greenhouses with day temperatures ranging from 14to 20° C., night temperatures ranging from 4 to 8° C., and light levelsranging from 3,000 to 5,000 foot-candles. Flowering stems used in thephotograph and the description were about 78 days old. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart except where general terms of ordinary dictionarysignificance are used.
